I don't see a disk image in the list
If you don't see a disk image in the list in the Disk Utility, you need to "attach" it to Disk Utility.
To open a disk image:
- Choose File > Open Disk Image, select the disk image and click Open.
- Drag the disk image file from the Finder to the Disk Utility window.
Disk Utility displays disk images below disks and volumes connected to your computer.
Disk images remain in the list until you drag them from the list or they are no longer available on the disk or volume.
